Be it lLlluWl: thot l, logo r '1. this, 2. citizen of the United Photos,roshling itl'. Worcrst r, in the county ol Worcester and lltote ol'. ,s,have invented certain new and nsolul l1 vcnionts in l i eltlleplenishing Looms, 0i which the following is :1. specific tron.

My invention relates to welt replenishing loorhs, and to that class oflooms which have lilling changing mochanisni, and shilting or dropshuttle boxes, and filling of filling in the active shuttle, and causethe filling change mechanism to operate to supply fresh filling; and myinvention particularly relates to the class of looms shown described inU. 3. Letters Patent No. 665,8l5, of January S, 1901., in which thefilling feelers of the filling detector mechanism move'up and down withthe shifting or drop shuttle boxes, so that the lilling lcolers willalways nioin tsln proper relation to the shuttle boxes, and feel for anddetect the practical exhaustion of filling in the active shuttle.

The object ol my invention is to improve upon the filling detectormechanism in the class ol looms referred to, and. to do away with theemploynient of electricity, or a nmgnotized leeler in connection with.the filling detector mechanism, and to provide it mechanloelers for eachshuttle box are preferably made in pairs, of caliper form, and areadapted 'to enter open-- ings in the lront of the shuttle box and theshuttle, and engage the filling carrier or bobbin above mid below itscentral longitudinal axis.

My invention consists in certain novel lez turos of construction of myiinprovexnents, as will be herein-- 1 v I have shown in the drawings indetached portion oi a loom having a magazine of the woll known Northroptype, shown and described in U. S.

has a hub 24 adjusolly secured by a screw 25 on a vertically moving rod:36. The rod 2t; has the saintvertical movement as the litter rod 7 andshuttle boxes (3 carried thereon. 'llu-re is a guide. not shown, for thelower end of the rod 20. The rod 2U has secured upon its upper end, inthis instance by nuts 27 and 28, see Fig. 3, a stand 29, which has avertical movement with the rod 2o, an 1 has its vertically extendingportion 29 made with sideextensions to extend into and travel in guidesor ways in a plate 30, secured to the extensions 21 on the b'racktt 21,see Fig. 1. The stand 29 carries two vertically extending pins .or studs3i and 32. on which ale loosely mounted the hubs of levers 33 and 34which hubs are supported on the adjustable collars 31 and 32 on the pins31 and 32. see Fig. -l. The leversi33 and 34 arc-connected by a link 35.to cause said lovers to have a parallel motion. The link 35 has twoupwardly extending pins 35 last thereon, which have in this'instanee bya screw 37, a second feeler blade 38. The two blades 38 and 38 aresubstantially parallel to. each' other, and extend one above the other,

, with their inner ends adapted to enter, as the lay beats up, anopening or openings in the shuttle binder 39, and openings in the frontside of the shuttle, to engage the filling on the bobbin, in case of aiull b0bbin,see Fig. 2, or to receive the bobbin between them in case ofa substantial exhausted bobbin, see Fig. l, and thus act as fillingdetectors. One of tho levers, preferably the inner lever 33, has an arm3: extending out from the hub of said lever, and when the fillingfeelers 38 are in their inward position, with the filling on the bobbinin the shuttle substantially exhausted, as shown in Figs. 1 and 4', thefree end of the arm 33 is in engagement with the inner edge of a bar-10, to hold said bar against a pin 41, which extends into a recess 40in the rear edge of said bar 40. The outer free end of the bar 40 issupported on and guided by the extension 21 on the bracket ill, and theinner end of said bar is pivot-ally ,oi the angle lever 20, the hub 20of which is pivotally mounted on a stud 20 see Fig. 1, the other arm ofthe angle lever 20 is connected with the vertically mo"\'-- ing plate19, as'above described. A lei spring 46 is attached at one end to thestand 21" f bearsat its other lree end against the inner edge or the bar46, and acts to move said bar outwardly. A pin 4]. wnieh is adapted toextend at its inner end into the recess 20 in the outer edge of the bar10, isadji-istably secured by a screw 47 in a hub 4-7 on a sliding bar48, which is pivotally connected at its inner end by a stud 50 to aprojection 5.1 on a collar 51, secured by two niits 52 on one end of alongitudiiutl sliding rod 53. The rod.53 is supported and has itsbearing in a hub on the end of the stand 21. 'lhe other end of the rod53 is pivotally connected with one arm or" an angle lever 54, the hub ofwhich is pivotally mounted on a pin 55, seeFigs. 3 and 5. The other armof the angle lever 54 is connected through a link 56 with a lever57,9which has a rocking up and down movement communicated thereto atregular intervals, from a earn, not shown, on a driven part of the loom;The outer end oi the sliding bar 48 extends through an opening. in thesupport 21, secured to the bracket 21, see Fig. 4. and is bent at anangle to the main portion, and has a hub 48 at its extreme end, in whichis secured, by a screw 58, a, pin 59. There are a set of levers 33 and34. and a link 35, a wire 36, bloc-K36, and l'eeler blades 38, and 38for each shuttle box of the drop shuttle boxes, in this inslai (to twodrop shuttle boxes are shown, and two sets of lovers 33 and 34, andparts connected therewith. in case of additional shuttle boxes, therewill be additional sets of levers 33 and 34 and partsconnectedtherewith.

The opemtionot' niy iniproven'ients above described,

will be readily understood by those skilled in the art from the abovedescription in connection, with the drawings.

When the lilling on the bobbin in the running shuttle in the top box issubstantially exhausted, as shown in Figs. 1. and 4. the parts of myfilling detector mechanisiu. when the lay isat its forward stroke, willbe in the position shown in Figs. 1, and 4, the arm 33 being inengagement. with the inner edge of the sliding rod 41), and holding thenotch 40, in the outer edge of said 41. The longitudinal movement ofthe. sliding rodB, in the manner above described, in an outwarddirection, will carry the sliding rod 40 with it, and through the rod 45will move the angle lever 20 to raise the plate ll), against the actionof the spring 19", and allow the spring l7.to move the lever 16, anddisengage the hook arm 15, to allow the dagger 13, operated by thespring 14, to move into the path of. the hunter on the lay, and throughthe engagement of the hunter with the dagger, operate the translerrer 11to supply fresh filling, in the usual and well known way.

The operation of the filling detector mechanism is so timed, that alterthe filling feelers or blades 38 and 38 have indicated for a'supplyoffresh filling, the shuttle, having the substantially exhausted bobbintherein, is thrown to the other side of the loom to receive a freshbobbin. When the bobbin in the runningshuttle is full ol filling, anduntil it becomes substantially exhausted, the engagementoi the endsotthe filling detectors or blades 38 and 38 with the filling on thebobbin, as shown in Fig. 2, and in the lower boy. in Fig. 4, as the layheats up, moves backwardly said blades, and with thorn the link 36and'the levers 33 and 34, into the position shown in Fig. 2, disengagingthe arm 33 from the rear edge 01' th'esliding'oar 40, leaving saidbarfiee'to move on its pivt'ital support, and thus allow tbe'i'nriey end ofthe pin 41 to move out of the notch 20 in said bar 40, in themovgt-nient oi the sliding bar 48, without moving said bar 40 andoperating the filling changing mechahism. On the return movement of thesliding sliding rod, in engagement with the inner end of the pin its'bar'48, the pin 59 will engage the arm 33 on the lever 33, and movesaid lever, to cause the free-end thereof to engage the inner edge orthe sliding bar 4(1 at 'r 'the pin 41 passes into the notch :40, asshown in Fig 1, and this opera tion is repeated at regular intervals asthe loom operates.

Referring now to the modified construction shown in Figs. 6 to 9,inclusive. In said figures'is shown gne filling detector mechanism forone shuttle born The same figures of reference are used on the partscorrespond ing to similarpartsin the other figures. The sliding bar 48in Fig. '6 is not provided with the extended end carrying the pin' 59,shown in Figc 1, as the lever 33 is spring actuated, to cause theifeeler. blades 38 and 38* to feel into the shuttle box. In thisinstance a lightcoil leaf spring 60,.oi a watch-spring type, is attachedat one end to the projecting arm 33, and at its other end to the a onthe other end of the link 35. The feeler blade Bil/has secured thereto,by a screw 62, a block 63, the upper\end nd of which is preferablyslightly curved or rounded has secured thereto by two screws 64 and 64,the outerend of the upper feeler blade 38, see Fig. 8. By meansof therounded surface on the iipper end of the block 63, the horizontal planeof the ieeler blade 38 may be adjusted, to cause the inner end of thefebler blade to be nearer the end. of the fecler blade 38, by turning inthe inner screw 64, and turning out the outer screw 64, as shown in Fig.7, or the inner end of the focler bladc 38 may borne. ed fartherawayfrom the color blade 38, as shown in Fig. 8, by turning in the outerscrew 64, and by turning out the inner screw 64. By means of thisadjustment of the feelor blades, the amount of filling to be left on thebobbin may be regulated.

In Fig. Slinstead of the two iecler blades 38 and 38, a single ieelerblade 38 is shown,-which is adapted to entor a single hole in theshuttle, and engage the bobbin at one point, preferably the centralfront portion, todetcct substantial exhaustion of filling thereon.

It will be understood that the loom will continud' to operate normally,until on the substantial exhausti u of filling on the bobbin'inthelriuining shuttle, tile iceler blades 38 and 38 indicate for a changeof filling,

when the filling changing mechanism will operate in the, manner abovedescribed, to supply fresh lilling.

It will be understood that the details of construction of myimprovements may be varied if desired, and they may be adapted to beapplied to wci't replenishing looms oi: different kinds, in which one ormore shuttle boxes, at the end of the loom opposite from the magazine,are used. l
